“…In the present study, the frequencies of unilateral contact in the RCP for both the pain patients and the clicking patients showed similar values to other studies (Egermark‐Eriksson, Carlsson & Magnusson, 1987; Pullinger et al ., 1993; Westling, 1995). Although Egermark‐Eriksson et al .…”

“…Rosenthal and Burch (1975) showed three basic patterns related to occlusal interferences and illustrated the site of muscle tenderness on the occlusal interference side. Up to the present only a few studies concerned with the relation between the symptomatic side and the occlusal interference side have been published (Linde & Isacsson, 1990; Westling, 1995).…”

This study aimed to investigate the relationship between the facial side of pain or clicking symptoms and the side of occlusal interference, and to examine the features of pain and clicking patients in terms of frequencies of occlusal interferences in relation to the symptomatic side. Occlusal conditions in 31 pain patients and 40 clicking patients were investigated just after the relief of pain or clicking solely by means of bite plane therapy. The symptomatic side did not associate with the side of fewer occlusal contacts in intercuspal position, no canine contact on the working side, occlusal contact on the non-working side, or unilateral contact in retruded contact position. The results of this study suggest that pain or clicking does not necessarily tend to appear on the side of these occlusal interferences. Additionally, characteristic inclination for pain and clicking patients in terms of frequencies of occlusal interferences in relation to the symptomatic side was not identified.

“…It is also not recommended to draw conclusions on the aetiology of TMJ pathology from these parameters. There was no statistically significant association with clicking and joint tenderness according to the length and symmetry of the RCP–ICP slide or unilateral contact in RCP (Pullinger et al ., 1988Westling, 1995). The Angle classes or a crossbite malocclusion were not significant factors in the development of TMJ symptoms (Butler, Folke & Bandt, 1975; Grosfeld & Czarnecka, 1977; Lieberman et al ., 1985).…”

This study compared the mandibular position at chin-point guided jaw closure, intercuspation and final deglutition (position at the end of swallowing) in 159 asymptomatic subjects and 142 subjects with symptoms in the craniomandibular system. The symptomatic subjects were assigned to four groups showing an adapted centric posture, pain, luxation with reduction of the temporomandibular joint and pain with luxation and reduction. Computer equipment aided recording of hinge axis movements in three dimensions. While the three positions differed significantly in anterior-posterior direction on both sides and in inferior-superior direction on the right, a significant difference between asymptomatic and symptomatic subjects existed only in final deglutition on the left side and in the anterior-posterior location of the guided closure. Final deglutition did not coincide with the guided closure or the intercuspation in approximately 89%. A proportionally large standard deviation gave evidence against a strict relationship of the three positions in asymptomatic and symptomatic subjects. Because of this variability, final deglutition was not recommended for verification of centric relation or the intercuspal position.

“…Excessive load on the masticatory system due to occlusal instability eventually gives rise to temporomandibular damage. The influence of occlusion on the onset of TMD is debated and still a source of controversy [10][11][12][13][14]. The detailed, exhaustive study of these factors will help in furthering the knowledge on the possible existence of the association.…”

Context: Dental researchers are contradictory in their opinion on the role of occlusion in TMD. Occlusal evaluation of both conventional and digital methods in TMD patients will provide the accurate information about the factors accountable for occlusal instability. Identifying the factors responsible will facilitate precise diagnosis and treatment for TMD. Aim:The Aim of the study was to determine the dynamic occlusal parameters strongly associated with the etiology of Temporomandibular disorders. Material and Methods:Study group consisted of 100 patients; it included 50 patients with normal TMJ(Group I) and remaining 50 patients had a minimum of one positive sign or symptom of Temporomandibular disorder (GroupII). The patient's dynamic occlusal contacts were evaluated by both conventional and digital methods. The Articulating paper was utilized for conventional occlusion analysis. During conventional analysis centric, lateral and protrusive interferences were evaluated along with loss of vertical dimension. Digital occlusal analysis was performed with T-Scan III. Clusion time, disclusion times were recorded for both groups.Chi-square and Student 't' statistical analyses were performed to ascertain the association and statistically significant difference between the groups using SPSS19.Results: Group II patients predominantly (66%)had Groupfunction occlusion compared to Group I subject. Centric slide more than 2 mm found to have strong influence (p-value 0.008) on the etiology of TMD. Among the occlusal interferences evaluated balanced side interferences had a strong correlation with TMD with P-value of 0.003. Working side interferences, protrusive interferences had a p-value of 0.157, 0.826 respectively, indicating weak association. T-Scan analysis showed Group I had 0.689, 0.9136, 0.7952, 0.9794 seconds of clusion, left, right, protrusive disclusion time respectively compared to corresponding 1.862, 1.7995, 1.6978, 1.9296 seconds for Group II. Statistically significant difference (p≤0.05) was found between the mean values of both groups. Conclusion:Among the dynamic occlusal parameters evaluated centric slide and balancing side interferences were found to be highly influential in TMD etiology. TMD patients had prolonged clusion and disclusion times compared to healthy TMJ patients.SatheeSh B. haralur
